A 910-kg object is released from rest at an altitude of 1200 kmabove the north pole of the earth. If we ignore atmosphericfriction, with what speed does the object strike the surface of theearth?

(G = 6.67 * 10^-11 (Nm^2)/kg^2, M_earth = 5.97 10^24 kg, thepolar radius of the Earth is 6357 km)

A satellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. If a geosynchronous satellite isin an equatorial orbit, its position appears stationary withrespect to a ground station, and it is known as a geostationarysatellite.

Find the radius of the orbit of a geosynchronous satellite thatcircles the earth. (Note that is measured from the center of theearth, not the surface.) You may use the following constants:
The universal gravitational constant is . 6.67 x 10^-11 N *m^2/kg^2
The mass of the earth is . 5.98 x 10^24 kg
The radius of the earth is . 6.38 x 10^6 m

A satellite is in a circular orbit about the Earth at a distance of2.5 Earth radii above the surface. What is the speed of thesatellite? (The radius of the Earth is 6.4 x 10^6 m, and G = 6.67 x10^-11 N * m^2/kg^2)

Find the radius R of the orbit of a geosynchronous satellite that circles the earth. (Note that R is measured from the center of the earth, not the surface.) You may use the following constants: • The universal gravitational constant G is 6.67 x 10^-11 N -m²/kg • The mass of the earth is 5.98 x 10²⁴ kg. • The radius of the earth is 6.38 x 10⁶ m.

Give the orbital radius In meters to three significant figures.
